A project log for Raspberry Pi with 2.8 inch touch screen

I'm thinking about recreating Adafruit's PiGRRL, except in a different form factor

I have been snowed in recently, and besides playing video games all day, I've done a little work on some of my projects. I soldered both of the batteries together in parallel, so the battery life will be increased and I can still use the same charger. I did some research on if this was alright, and plenty of R/C enthusiasts do it all the time. Since they are the same size, the cells should balance. If you choose to do something similar, I would recommend draining the batteries first so you don't have to worry about shorting the leads and potentially damaging the LiPos. Here's my work, I taped them to an old credit card currently for mockup purposes:

I also disassembled a SNES controller that doesn't work any more. I have a couple more, and since I was gonna use it for this project, I don't care to sacrifice it. I'm not sure what was wrong with it, no commands would register at all, so I believe the chip in it went bad, or perhaps it's missing a connection to it. A brief inspection of the board didn't yield any answers, so it's on the altar to the god of h@x. Here's the controls set out the way I would like to see them in the final form:

I'll need to trim the elastomers to fit inside the yet-to-be designed enclosure, but it looks like it will be comfortable for some classic gaming on the go! I need to cut up the PCB for the controller and wire it to the GPIO on the Pi next. I'm not sure how I'm going to do it yet, since the screen is clipped onto all the pins, but I'll figure something out.
